The target electronic device can execute a target activation operation corresponding to the target activation instruction by using the target personalized data activation program, that is, activate the target personalized data by using the target personalized data activation program, so as to realize activation of the target payment token.

In the embodiment of the application, upon reception of a target activation instruction and a payment token to be activated corresponding to a payment card account number which needs to be activated sent by a target server, a target payment token in a target personalized data which belongs to a transaction cart having a same type as that indicated in the target activation instruction can be directly updated as the payment token to be activated and the updated target payment token can be set to be in an activated state, so it is possible to directly update the target payment token in the target personalized data by using the payment token to be activated and to activate the updated target payment token without deleting an activated payment token and its corresponding personalized data in the process of activating the payment token to be activated, thereby reducing processes of deleting personalized data, verifying personalized data and downloading personalized data in the process of activating the payment token to be activated, and thus avoiding errors caused by the above-mentioned processes when setting a default payment card so as to improve a success rate of setting the default payment card.

In some embodiments of the application, in a case where the payment card account number is a default payment card account number which needs to be set, before the S510, the data processing method may further include: receiving the default payment card account number which needs to be set; and generating a default card setting request according to the default payment card account number which needs to be set; and sending the default card setting request to the target server, wherein the default card setting request is configured to request the target server to feed back the target activation data and the target activation instruction corresponding to the default payment card account number which needs to be set.

Specifically, a user may select any payment card account number from at least one payment card account number bound to the target electronic device which is displayed in an application interface of a financial application of the target electronic device as the default payment card account number which needs to be set. The electronic device may generate a default card setting request according to the default payment card account number which needs to be set and the target electronic device identifier, and then send the default card setting request to the Internet financial platform server, and the Internet financial platform server can feed back the target activation data and the target activation instructions that correspond to the default payment card account number which needs to be set. The method for the Internet financial platform server to feed back the target activation data and the target activation instructions will be described in detail later.

In some embodiments of the application, the target electronic device identifier may be an internet protocol (Internet Protocol, IP) address of the target electronic device. In some other embodiments, the target electronic device identifier may be a device identity code (Identity Document, ID) of the target electronic device.

In some embodiments of the application, in a case where the payment card account number is a default payment card account number which needs to be set, since no other payment token has been activated in the target electronic device before, the target personalized data may be personalized data which is stored in the target security element of the target electronic device and for which a payment token is in an inactivated state.

In some embodiments, when receiving the target activation data and the target activation instruction sent by the target server, the target electronic device may directly execute the S520 if the target personalized data has been stored in the target security element of the target electronic device.

In some other embodiments, when receiving the target activation data and the target activation instruction sent by the target server, the target activation data received by the target electronic device may further includes the target personalized data if the target personalized data has not been stored in the target security element of the target electronic device. In some embodiments, before the S520, the data processing method may further include: storing the target personalized data in the target security element.

Therefore, in a case where the target security element of the target electronic device has not been stored the target personalized data, the target personalized data may be loaded into the target security element first, so as to ensure reliability of the payment token to be activated corresponding to the payment card account number which needs to be activated.

In some embodiments of the application, in a case where the payment card account number is a default payment card account number which needs to be changed, before the S510, the data processing method may further include: receiving the default payment card account number which needs to be changed; generating a default card changing request according to the default payment card account number which needs to be changed; and sending the default card changing request to the target server, wherein the default card changing request is configured to request the target server to feed back the target activation data and the target activation instruction corresponding to the default payment card account number which needs to be changed.

Specifically, a user may select any payment card account number other than a payment card account number that has been set as a payment card account number of a default payment card from at least one payment card account number bound to the target electronic device which is displayed in an application interface of a financial application of the target electronic device as the default payment card account number which needs to be changed. The electronic device may generate a default card changing request according to the default payment card account number which needs to be changed and the target electronic device identifier of the target electronic device, such that the Internet financial platform server feeds back the target activation data and the target activation instructions corresponding to the default payment card account number which needs to be changed. The method for the Internet financial platform server to feeds back the target activation data and the target activation instructions will be described in detail later.

In some embodiments of the application, in a case where the payment card account number which needs to be activated is a default payment card account number which needs to be changed, another payment token has already been activated in the target electronic device. Therefore, in some embodiments, the target personalized data may be personalized data which is stored in the target security element of the target electronic device and for which a payment token is in an activated state. In some other embodiments, the target personalized data may be personalized data which is stored in the target security element and for which a payment token is in an inactivated state, which is not limited herein.

In some embodiments, when receiving the target activation data and the target activation instruction sent by the target server, the target electronic device may directly execute the S520 if the target personalized data has been stored in the target security element of the target electronic device.

In some other embodiments, when receiving the target activation data and the target activation instruction sent by the target server, in the case that the target personalized data has not been stored in the target security element of the target electronic device, the target activation data received by the target electronic device may further include the target personalized data. In some embodiments, before the S520, the data processing method may further include: storing the target personalized data in the target security element.

Therefore, in the case where the target security element of the target electronic device has not been stored the target personalized data, the target personalized data may be loaded into the target security element first, so as to ensure reliability of the payment token to be activated corresponding to the payment card account number which needs to be activated.

In some embodiments of the application, in a case where the target personalized data is personalized data which is stored in the target security element and for which a payment token is in an inactivated state, after the S530, the data processing method may further include: setting an activated payment token other than the updated target payment token to be in an inactivated state.

Since another payment token has been activated in the target electronic device before, it is necessary to set an activated payment token other than the updated target payment token, that is, a payment token which is in an activated state, to be in an inactivated state in order to avoid errors during reading by the acquiring device the target payment token in the target security element of the target electronic device.

In the embodiment of the application, the target electronic device may execute a target restoration operation corresponding to the target activation instruction by using a target personalized data activation program, that is, set personalized data of a payment token which has been in an activated state to be in an inactivated state by using the target personalized data activation program, which cancel activation of the payment token which is already in the activated state, so as to ensure that only one payment token in the target security element of the target electronic device is in the activated state.

FIG. 6 shows a schematic flowchart of another example of a data processing method according to the application.

In some embodiments of the application, the method shown in FIG. 6 may be performed by the Internet financial platform server 120 shown in FIG. 1 to FIG. 4 .

As shown in FIG. 6 , the data processing method may include the following steps.

At S610, a payment token to be activated which is stored in association with a payment card account number which needs to be activated and a target activation instruction are acquired.

A transaction card type of the payment card account number which needs to be activated is same as a transaction card type indicated by the target activation instruction.

Specifically, the Internet financial platform server may acquire a payment token to be activated from locally stored payment tokens which is stored in association with a payment card account number which needs to be activated, and acquire a target activation instruction from locally stored activation instructions, wherein a transaction card type indicated by the target activation instruction is same as a transaction card type of the payment card account number which needs to be activated.

At S620, target activation data is generated according to the payment token to be activated.

In some embodiments of the application, the payment token to be activated may be loaded into a data packet corresponding to the target activation data, so as to generate the target activation data.

At S630, the target activation data and the target activation instruction are sent to a target electronic device.

The target activation instruction is configured to instruct the target electronic device to update a target payment token in target personalized data to the payment token to be activated and set the updated target payment token to be in an activated state, wherein a transaction card type indicated by the target personalized data is same as the transaction card type indicated by the target activation instruction. The method for activating the payment token to be activated by the target electronic device has been described in detail in the method embodiment shown in FIG. 5 , and will not be repeated here.

In the embodiment of the application, after a payment token to be activated which is stored in association with a payment card account number which needs to be activated and a target activation instruction which indicates a same transaction card type as that of the payment card account number which needs to be activated, target activation data is generated according to the payment token to be activated, and the target activation data and the target activation instruction are sent to the target electronic device, so that the target electronic device updates a target activation token in target personalized data of the same transaction card type as that indicated by the target activation instruction to be the payment token to be activated, and sets the updated target payment token to be in an activated state, and thus the target activation token in the target personalized data can be updated directly with the payment token to be activated and the updated target payment token can be activated accordingly without deleting an activated payment token and its corresponding personalized data in a process of activating the payment token to be activated, thereby reducing processes of deleting personalized data, verifying personalized data and downloading personalized data in the process of activating the payment token to be activated, and thus avoiding errors caused by the above-mentioned processes when setting a default payment card so as to improve a success rate of setting the default payment card.

In another embodiment of the application, before the S620, the data processing method may further include: acquiring the target personalized data, in order to avoid failure to activate the payment token to be activated caused by that the target personalized data has not been stored in the target security element of the target electronic device.

Correspondingly, the S620 may specifically include: generating the target activation data according to the payment token to be activated and the target personalized data.

Therefore, the Internet financial platform server can acquire the target personalized data from locally stored personalized data, wherein the transaction card type indicated by the target personalized data is same as a transaction card type indicated by the target activation instruction, and load the target personalized data together with the payment token to be activated into a data package corresponding to the target activation data, so as to generate the target activation data.

In some embodiments of the application, in order to further improve reliability of the target electronic device activating the payment token to be activated, before acquiring the target personalized data, the data processing method may further include: sending a data query request to the target electronic device, wherein the data query request is configured to query in a target security element of the target electronic device for the target personalized data; and receiving a data query result fed back by the target electronic device.

Correspondingly, the acquiring the target personalized data may specifically include: acquiring the target personalized data in a case where the data query result indicates that the target personalized data has not been found in the target security element.

Specifically, before the sending the target activation data and the target activation instruction to the target electronic device, the Internet financial platform server needs to first send a data query request to the target electronic device to query whether the target security element of the target electronic device has stored the target personalized data. After receiving the data query request, the target electronic device can query whether the target personalized data has been stored in the target security element, and feedback a data query result to the Internet financial platform server. The Internet financial platform server can receive the data query result fed back by the target electronic device, and directly generate the target activation data according to the payment token to be activated if the data query result indicates that the target personalized data has been found in the target security element; and acquire the target personalized data if the data query result indicates that the target personalized data has not been found in the target security element and generate the target activation data according to the payment token to be activated and the target personalized data.

Therefore, in the embodiment of the application, it may be first determined whether the target security element of the target electronic device stores the target personalized data required to activate the payment token to be activated, and then, according to a result of the determination, it is determined whether to send the target personalized data to the target electronic device to enable the target electronic device to reliably implement activation of the payment token to be activated.

In the embodiment of the application, the target personalized data required for the payment token to be activated may be personalized data of the same transaction card type as the transaction card type indicated by the target activation instruction. A payment card type may correspond to a set of personalized data.

For example, a credit card type may correspond to a set of personalized data, and a debit card type may correspond to a set of personalized data.

A payment card type may correspond to a set of general personalized data, which can eliminate differences in personalized data among various payment card issuers, and improve compatibility between a device card and an industrial machine.

In an embodiment of the application, the payment card account number which needs to be activated may include a default payment card account number which needs to be set.

Correspondingly, before the S610, the data processing method may further include: receiving a default card setting request sent by the target electronic device; and parsing, in response to the default card setting request, the default card setting request to obtain information of the default card setting request, wherein the information of the default card setting request includes the default payment card account number which needs to be set.

After receiving the default card setting request, the Internet finance platform server can parse, in response to the default card setting request, the default card setting request to obtain the default payment card account number which needs to be set and the target electronic device identifier of the target electronic device, and then query for a payment token which is stored in association with the default payment card account number which needs to be set and use it as the payment token to be activated.

Thus, in a case where the user needs to set a default card for the target electronic device, the Internet financial platform server can send the target activation data and the target activation instruction corresponding to the default payment card account number which needs to be set to the target electronic device.

In some embodiments of the application, in a case where the payment card account number which needs to be activated is a default payment card account number which needs to be set, after the S630, the data processing method may further include: receiving an activation result sent by the target electronic device, wherein the activation result is configured to indicate that the target electronic device has set the payment token to be activated to be in an activated state; setting, in response to the activation result, a payment card attribute corresponding to the payment card account number which needs to be activated as a target attribute, wherein the target attribute indicates a default payment card for the target electronic device; setting a token state corresponding to the payment token to be activated to be an activated state; and establishing an association relationship between the payment token to be activated and the target electronic device.

Specifically, after executing the target activation instruction, the target electronic device feedbacks an activation result to the Internet financial platform server. The activation result may be configured to indicate that the target electronic device has set the payment token to be activated to be in an activated state, or indicate that the target electronic device has failed to activate the payment token to be activated.

The Internet financial platform server may, after sending the target activation data and the target activation instruction to the target electronic device, receive the activation result sent by the target electronic device, and set a payment card attribute corresponding to the payment card account number which needs to be activated to indicate a default payment card for the target electronic device in a case where the activation result is configured to indicate that the target electronic device has set the payment token to be activated to be in an activated state, set a token state corresponding to the payment token to be activated to be an activated state, and establish an association relationship between the payment token to be activated and the target electronic device identifier of the target electronic device, which enables the NFC payment function of the target electronic device to be available.

Then, the Internet financial platform server may feedback first prompt information to the target electronic device. The first prompt information is configured to prompt the user that a default payment card has been successfully set for the target electronic device, and the target electronic device can use the NFC payment function normally through the default payment card.

In the embodiment of the application, the bound payment card account number and the personalized data in the target electronic device are in a loosely coupled relationship, that is, a dynamic mapping relationship. A mapping relationship between the default payment card account number and the target electronic device can be established by establishing an association relationship between the payment token to be activated and the target electronic device.

In some other embodiments of the application, the payment card account number which needs to be activated may include a default payment card account number which needs to be changed.

Correspondingly, before the S610, the data processing method may further include: receiving a default card changing request sent by the target electronic device; and parsing, in response to the default card changing request, the default card changing request to obtain information of the default card changing request, wherein the information of the default card changing request includes the default payment card account number which needs to be changed.

After receiving the default card changing request, the Internet finance platform server can parse, in response to the default card changing request, the default card changing request to obtain the default payment card account number which needs to be changed and the target electronic device identifier of the target electronic device, and then query for a payment token which is stored in association with the default payment card account number which needs to be changed and use it as the payment token to be activated.

Thus, in a case where the user needs to change a default card for the target electronic device, the Internet financial platform server can send the target activation data and the target activation instruction corresponding to the default payment card account number which needs to be changed to the target electronic device.

In some embodiments of the application, in a case where the payment card account number which needs to be activated is a default payment card account which needs to be changed, before the above-mentioned data query request is sent to the target electronic device, the data processing method may further include: acquiring a target payment card account number, wherein a payment card attribute corresponding to the target payment card account number is a target attribute, and the target attribute indicates a default payment card for the target electronic device.

Correspondingly, the sending the data query request to the target electronic device may specifically include: sending the data query request to the target electronic device in a case where a payment card type of the target payment card account number is different from a payment card type of the default payment card account number which needs to be changed.

Before sending the data query request to the target electronic device, the Internet financial platform server may query a current target payment card account number of the target electronic device whose payment card attribute indicates a default payment card, that is, the original default payment card account number. Then, a payment card type of the target payment card account number is compared with a payment card type of the default payment card account number which needs to be changed. Finally, if a result of the comparison is that the payment card type of the target payment card account number is the same as the payment card type of the default payment card account number which needs to be changed, it means that the target personalized data has been stored in the target security element of the target electronic device, so the target activation data may be directly generated according to the payment token to be activated. If the result of the comparison indicates that the payment card type of the target payment card account number is different from the payment card type of the default payment card account number which needs to be changed, it means that the target security element of the target electronic device has not stored the target personalized data, so it is necessary to send the target personalized data to the target electronic device, and thus the target personalized data is acquired, and the target activation data is then generated according to the payment token to be activated and the target personalized data.

In other embodiments of the application, in a case where the payment card account number which needs to be activated is a default payment card account which needs to be changed, after the S630, the data processing method may further include: receiving an activation result sent by the target electronic device, wherein the activation result is configured to indicate that the target electronic device has set the payment token to be activated to be in an activated state; setting a payment card attribute corresponding to the payment card account number which needs to be activated as a target attribute and setting a payment card attribute corresponding to the target payment card account number as a non-target attribute in response to the activation result; setting a token state corresponding to the payment token to be activated to an activated state, and setting a token state corresponding to the target payment token which is stored in association with the target payment card account number to an inactivated state; and establishing an association relationship between the payment token to be activated and the target electronic device, and deleting an association relationship between the target payment token and the target electronic device.

Specifically, after executing the target activation instruction, the target electronic device feedbacks an activation result to the Internet financial platform server. The activation result may be configured to indicate that the target electronic device has set the payment token to be activated to be in an activated state, or indicate that the target electronic device has failed to activate the payment token to be activated.

The Internet financial platform server may, after sending the target activation data and the target activation instruction to the target electronic device, receive the activation result sent by the target electronic device, and in a case where the activation result is configured to indicate that the target electronic device has set the payment token to be activated to be in an activated state, firstly set a payment card attribute corresponding to the payment card account number which needs to be activated to indicate a default payment card for the target electronic device and set a payment card attribute corresponding to the original default payment card account number to be in an inactivated state, then set a token state corresponding to the payment token which to be activated to be an activated state, and finally establish an association relationship between the payment token to be activated and the target electronic device identifier of the target electronic device, which enables the payment token to be activated to become a new target payment token, and then deleting an association relationship between the original target payment token to be activated and the target electronic device identifier of the target electronic device.

In some embodiments of the application, the Internet financial platform server may feedback second prompt information to the target electronic device. The second prompt information may be configured to prompt the user that the default payment card for the target electronic device has been successfully changed, and the target electronic device can use the NFC payment function normally through the new default payment card.

Therefore, in the embodiment of the application, A mapping relationship between the default payment card account number and the target electronic device can be changed by establishing an association relationship between the payment token to be activated and the target electronic device and deleting an association relationship between the original target payment token and the target electronic device.

In still some other embodiments of the application, before the S610, the data processing method may further include: receiving a payment card binding request sent by the target electronic device; parsing, in response to the payment card binding request, the payment card binding request to obtain information of the payment card binding request, wherein the information of the payment card binding request includes a payment card account number which needs to be bound; generating a token generation request according to the payment card account number which needs to be bound; sending the token generation request to a payment token management server, wherein the token generation request is configured to request the payment token management server to generate a payment token corresponding to the payment card account number which needs to be bound; receiving the payment token corresponding to the payment card account number which needs to be bound fed back by the payment token management server; and storing the payment card account number which needs to be bound and the payment token corresponding to the payment card account number which needs to be bound in association with each other.

The user can first login an account of a financial application of the target electronic device to make the financial application be in a login state, and select in an application interface of the financial application a target electronic device bound to the account, that is, an electronic device that the user is operating. Then, the user can add a payment card account number for being bound to the target electronic device in the application interface of the financial application as the payment card account number which needs to be bound, so that the target electronic device can generate a payment card binding request according to the payment card account number which needs to be bound. Next, the target electronic device may send the payment card binding request to the Internet financial platform server.

After receiving the payment card binding request, the Internet financial platform server can parse the payment card binding request to obtain the payment card account number which needs to be bound and the target electronic device identifier. According to the payment card account number which needs to be bound, a token generation request is generated, and the token generation request is sent to the payment token management server.

In some embodiments, the payment token management server may be the TSP platform server 130 shown in FIG. 2 to FIG. 4 . After receiving the token generation request, the TSP platform server may parse the token generation request to obtain the payment card account number which needs to be bound, then generate a payment token corresponding to the payment card account number which needs to be bound, and store the payment card account number which needs to be bound with the payment token corresponding to the payment card account number which needs to be bound in association with each other. The payment token corresponding to the payment card account number which needs to be bound is fed back to the Internet financial platform server.

The Internet finance platform server can receive the payment token corresponding to the payment card account number which needs to be bound fed back by the TSP platform server, and then store the payment card account number which needs to be bound and the payment token corresponding to the payment card account number which needs to be bound in association with each other, so that the payment token corresponding to the default payment card account number can be sent to the target electronic device when the user is setting or changing a default payment card account number for the target electronic device.

Further, the Internet financial platform server may send third prompt information to the target electronic device after the target payment card account number is bound to the target electronic device. The third prompt information is configured to prompt the user that the payment card account number which needs to be bound has been successfully bound to the target electronic device.

In the embodiment of the application, the TSP platform server may generate the payment token corresponding to the payment card account number which needs to be bound by using a preset token generation method.

For example, the token generation method may use a preset encryption algorithm to encrypt all digits of the payment card account number which needs to be bound to obtain an encrypted character string, and use the encrypted character string as the payment token corresponding to the payment card account number which needs to be bound. For another example, the token generation method may use a preset encryption algorithm to encrypt a part of digits of the payment card account number which needs to be bound to obtain an encrypted character string, and to perform splicing of unencrypted digits of the payment card account number which needs to be bound with the encrypted character string to obtain the payment token corresponding to the payment card account number which needs to be bound.

In some embodiments of the application, the Internet financial platform server may communicate with the TSP platform server through the TSM platform server, so as to improve data security.

In yet another embodiment of the application, the data processing method may further include: receive a state changing request; parsing in response to the state changing request, the state changing request to obtain information of the state changing request, wherein the information of the state changing request includes a payment card account number whose state needs to be changed and a target payment state of the target electronic device; acquiring a payment token whose state is to be changed which is stored in association with the payment card account number whose state needs to be changed; and updating a token state corresponding to the payment token whose state is to be changed to be the target payment state.

In some embodiments of the application, the state changing request is configured to request the Internet finance platform server to update a token state corresponding to a payment token whose state is to be changed and is stored in association with a payment card account number specified by the user whose state is to be changed to a target payment state specified by the user for the target electronic device. The state changing request may be a state changing request sent by the target electronic device, or a state changing request sent by any other electronic device other than the target electronic device, as long as the electronic device is installed with the financial application corresponding to the Internet financial platform and an account number logged in the financial application is bound to the target electronic device for which payment state of an NFC payment function needs to be changed.

Specifically, the user may first login an account in the financial application of the electronic device enable the financial application to be in a login state, and select a target electronic device to which the account has been bound in an application interface of the financial application. Then, the user may input a payment card account number whose state is to be changed and a target payment state of the target electronic device in the application interface of the financial application, wherein the target payment state may be a payment state of the target electronic device that the user wants it to be changed. The electronic device operated by the user can generate a state changing request according to the payment card account number whose state is to be changed and the target payment state, and send the state changing request to the Internet financial platform server.

In the embodiment of the application, the target payment state may include any one of an activated state, a loss-reported state, and an unbound state. The target payment state may be a normal state or an abnormal state, wherein the abnormal state may include any one of the loss-reported state and the unbound state, and the normal state may include an activated state.

The activated state means that the NFC payment function of the electronic device has been activated and is available. The loss-reported state means that the NFC payment function of the electronic device has been activated but is in a loss-report registration state. In the loss-reported state, the NFC payment function is suspended. The unbound state means that the NFC payment function of the electronic device has been activated and has not been bound with a payment card account number. In the unbound state, the NFC payment function is also suspended.

In the embodiment of the application, the target electronic device or any other electronic device may directly communicate with the Internet financial platform server.

In some embodiments of the application, the information of the state changing request information may further include the target electronic device identifier of the target electronic device.

That is, after the electronic device operated by the user receives the payment card account number whose state is to be changed and the target payment state of the target electronic device inputted by the user, the electronic device may acquire the target electronic device identifier corresponding to the target electronic device, and then generate a state changing request based on the target electronic device identifier, the payment card account number whose state is to be changed and the target payment state.

In some embodiments of the application, the Internet financial platform server may store the token state corresponding to the payment token. For example, the Internet financial platform server may add a state bit to the payment token, wherein the state bit is provided with a state value, and one state value corresponds to one token state, and different state values correspond to different token states. Moreover, the token state may be same as the payment state.

In these embodiments, since the token state is the same as the payment state, the Internet finance platform server may determine a target state value corresponding to a token state that is the same as the target payment state, and set the state bit of the payment token whose state is to be changed to be the target state value, so as to update the token state corresponding to the payment token whose state is to be changed to be the target payment state.

In the embodiment of the application, since one electronic device stores one payment token which is in an activated state, and a token state corresponding to each payment token is the same as the payment state, the Internet financial platform server can, according to a token state corresponding to a payment token, determine the payment state of the electronic device corresponding to the payment token, and then determine whether to execute a transaction corresponding to a transaction request that carries the payment token according to the payment state of the electronic device.

Therefore, it is possible to update the target payment state of the target electronic device with the target token state corresponding to the target payment token without deleting the target payment token in the target electronic device. Thus, it is possible to avoid a problem that a user cannot change the payment state of the target electronic device after the target electronic device is lost merely by updating the target payment state of the target payment token which is stored in the Internet financial platform server, thereby reducing a risk of the bank account associated with the target electronic device being stolen and used, and improving security of the user's bank account.

In the embodiment of the application, regardless of whether the payment card attribute corresponding to the payment card account number whose state needs to be changed indicates a non-default payment card for the target electronic device or a default payment card for the target electronic device, the token state corresponding to the payment token whose state is to be changed can be directly updated to the target payment state, and then the fourth prompt information is fed back to the target electronic device. The fourth prompt information is configured to prompt the user that the payment state of the payment card account number which is bound to the target electronic device and whose state needs to be changed has been changed to be the target payment state.

In some embodiments of the application, the information processing method may further include: receiving a transaction request sent by a target acquiring device; parsing the transaction request in response to the transaction request to obtain information of the transaction request, wherein the information of the transaction request includes the target payment token; querying for a token state corresponding to the target payment token; refusing to execute a transaction corresponding to the transaction request in a case where the token state corresponding to the target payment token is an abnormal state, wherein the abnormal state includes any one of a loss-reported state and an unbound state.

Specifically, when a user is using a target electronic device to implement payment, a merchant can read an activated payment token (i.e. the target payment token) stored in a target security element of the target electronic device through a target acquiring device. The target acquiring device generates a transaction request according to the target payment token, a target acquiring device identifier of the target acquiring device and transaction amount, and then send the transaction request to the Internet financial platform server.

The target acquiring device identifier may be an IP address of the target acquiring device, or may be a device ID of the target acquiring device.

The Internet financial platform server can receive the transaction request sent by the target acquiring device, analyze the transaction request to obtain the target payment token, the target acquiring device identifier and the transaction amount, and then query for a token state corresponding to the target payment token. The Internet financial platform server can refuse to execute a transaction corresponding to the transaction request when the token state corresponding to the target payment token is abnormal; query for a target transaction card account number which is stored in association with the target payment token when the token state corresponding to the target payment token is normal, and send the target transaction card account number, the target acquiring device identifier and the transaction amount to a server of a card issuer, so that the server of the card issuer finishes the transaction corresponding to the transaction request, by which a transfer of the transaction amount from the target transaction card account number to a transaction card account number corresponding to the target acquiring device identifier can be realized, and then feeds a transaction completion result to the Internet financial platform server. After receiving the transaction completion result, the Internet financial platform server may forward the transaction completion result to the target acquiring device.

In the embodiment of the application, the target acquiring device may directly communicate with the Internet financial platform server, and the target acquiring device may communicate with the Internet financial platform server through the acquiring platform server, which is not limited herein.

Therefore, after the target electronic device is lost, the user does not need to delete the personalized data or payment token which are stored in the target security element of the target electronic device, but only needs to change the payment state of the target electronic device to an abnormal state, so that the token state corresponding to the payment token in the target electronic device is changed to an abnormal state, and then when the target electronic device is used for payment again, the Internet financial platform server can refuse to execute the transaction, so as to avoid a bank account associated with the target electronic device from being stolen and used, thereby improving security of the user's bank account.

In some other embodiments of the application, in order to further reduce the risk of the payment card account associated with the target electronic device being stolen and used, after information of the state changing request is received in a case where the target payment state includes any one of the loss-reported state and the unbound state, the information processing method may further include: deleting an association relationship between the payment card account number whose state needs to be changed and the target electronic device in a case where a payment card attribute corresponding to the payment card account number whose state needs to be changed is a target attribute, wherein the target attribute indicates a default payment card for the target electronic device.

Specifically, the Internet financial platform server can determine whether there is an association relationship between the payment token and the target electronic device, and then determine a payment card attribute corresponding to a payment card account number which is stored in association with the payment token. If there is an association relationship between the payment token and the target electronic device, then the payment card attribute corresponding to the payment card account number which is stored in association with the payment token indicates a default payment card for the target electronic device, otherwise the payment card attribute corresponding to the payment card account number which is stored in association with the payment token indicates a non-default payment card for the target electronic device.

Since the payment token is stored in the target security element of the target electronic device only when the payment card attribute corresponding to the payment card account number which is stored in association with the payment token indicates a default payment card for the target electronic device, it requires only that the token state corresponding to the payment token whose state is to be changed is updated to the target payment state in a case where the payment card attribute corresponding to the payment card account number whose state needs to be changed indicates is a non-default payment card for the target electronic device. In the case where the payment card attribute corresponding to the payment card account number whose state needs to be changed indicates is a default payment card for the target electronic device, since the target security element of the target electronic device stores the payment token whose state is to be changed, it may further delete the association relationship between the payment card account number whose state needs to be changed and the target electronic device in order to avoid occurrence of errors in verification by the Internet financial platform server, so that when a transaction request corresponding to the payment token whose state is to be changed is received and it is determined that the target payment state is normal, it is further determined whether there is an association relationship between the payment token whose state is to be changed and the target electronic device, so as to determine whether to execute a transaction corresponding to the transaction request.

Specifically, if there is an association relationship between the payment token to be changed and the target electronic device, the transaction corresponding to the transaction request will be executed; and if there is no association between the payment token to be changed and the target electronic device, the transaction corresponding to the transaction request will not be executed.

Therefore, in the embodiment of the application, security of a bank account associated with the target electronic device can be further improved.

In still other embodiments of the application, after the refusing to execute the transaction corresponding to the transaction request, the information processing method may further include: generating transaction feedback information corresponding to the transaction request according to the token state corresponding to the target payment token; and sending the transaction feedback information to the target acquiring device.

Specifically, the Internet financial platform server can generate transaction feedback information corresponding to the transaction request, wherein the transaction feedback information carries the token state corresponding to the target payment token, and then sends the transaction feedback information to the target acquiring device. Upon reception of the transaction feedback information, the target acquiring device can display the token state corresponding to the target payment token carried in the transaction feedback information, so as to show the target payment state of the target electronic device to a transaction-related person (payee or payer) to inform reasons for refusal of the transaction to the transaction-related person.

Below, each process of data processing according to the embodiments of the application will be described in detail by taking FIG. 7 to FIG. 10 as examples.

At S801, a user opens an application interface of a financial application in a target electronic device, logs in an account in the application interface of the financial application, and selects, from at least one payment card account number bound with the target electronic device, a payment card account number which needs to be set as a default payment card for the target electronic device, and the target electronic device receives the payment card account number which needs to be set inputted by the user.

At S802, the target electronic device generates a default card setting request according to the payment card account number and a target electronic device identifier of the target electronic device.

At S803, the target electronic device sends the default card setting request to the Internet financial platform server.

At S804, the Internet financial platform server parses, in response to the default card setting request, the default card setting request to obtain the payment card account number and the target electronic device identifier.

At S805, the Internet financial platform server queries for a payment token which is stored in association with the payment card account number, and then sends a data query request to the target electronic device.

At S806, after receiving the data query request, the target electronic device may query in a target security element to determine whether there is personalized data corresponding to the payment token, and feeds a data query result back to the Internet financial platform server.

At S807, the Internet financial platform server may make a judgment on the data query result, and then the process goes to S808 if the data query result indicates that the personalized data corresponding to the payment token has been found in the target security element, and then the process goes to S809 if the data query result indicates that the personalized data corresponding to the payment token has not been found in the target security element.

At S808, the Internet financial platform server sends the payment token and an activation instruction corresponding to the payment token to the target electronic device, and then the process goes to S810.

At S809, the Internet financial platform server sends the payment token, the activation instruction corresponding to the payment token and the personalized data corresponding to the payment token to the target electronic device, and then the process goes to S810.

At S810, the target electronic device loads the payment token into the personalized data corresponding to the payment token and activates the payment token such that it is in an activated state.

At S811, the target electronic device sends an activation result which indicates that the target electronic device has set the payment token to be an activated state to the Internet financial platform server.

At S812, the Internet financial platform server sets a token state corresponding to the payment token to be an activated state, then sets a payment card attribute corresponding to a payment card account number which is stored in association with the payment token to be a default payment card for the target electronic device, and establishes an association relationship between the payment token and the target electronic device.

At S813, the Internet financial platform server feeds first prompt information back to the target electronic device.

At S814, the target electronic device displays the first display information to prompt the user that a default payment card has been successfully set for the target electronic device.

FIG. 9 shows a schematic flowchart of an example of a process for changing a default payment card according to an embodiment of the application.

As shown in FIG. 9 , the process for changing a default payment card may include S901-S913.

At S901, a user opens an application interface of a financial application in a target electronic device, logs in an account in the application interface of the financial application, and selects, from at least one payment card account number bound with the target electronic device, a payment card account number which needs to be changed as a new default payment card for the target electronic device, and the target electronic device receives the payment card account number which needs to be changed inputted by the user.

At S902, the target electronic device generates a default card changing request according to the payment card account number and a target electronic device identifier of the target electronic device.

At S903, the target electronic device sends the default card changing request to the Internet financial platform server.

At S904, the Internet financial platform server parses, in response to the default card changing request, the default card changing request to obtain the payment card account number and the target electronic device identifier.

At S905, the Internet financial platform server queries a payment token which is stored in association with the payment card account number and a payment token that is currently associated with the target electronic device identifier, and queries a payment card account number which is stored in association with the queried payment token, wherein the queried payment card account number is an original default payment card account number, that is, a payment card account number whose payment card attribute indicates a default payment card for the target electronic device.

At S906, the Internet financial platform server compares a payment card type of the original default payment card account number with a payment card type of the received payment card account number, and then the process goes to S907 if they are the same as each other, and the process goes to S908 if they are different from each other.

FIG. 10 shows a schematic flowchart of an example of a process for unbinding a payment card according to an embodiment of the application.

As shown in FIG. 10 , the process for unbinding a payment card may include S1001-S1012.

At S1001, a user opens an application interface of a financial application in a target electronic device, logs in an account in the application interface of the financial application, and selects a payment card account number which needs to be unbound from at least one payment card account number bound to the target electronic device, and the target electronic device receives the payment card account number which needs to be unbound and a target payment state of the target electronic device inputted by the user, wherein the target payment state is an unbound state.

At S1002, the target electronic device generates an unbinding request according to the target electronic device identifier, the payment card account number and the target payment state.

At S1003, the target electronic device sends the unbinding request to the Internet financial platform server.

At S1004, the Internet financial platform server parses, in response to the unbinding request, the unbinding request to obtain the target electronic device identifier, the payment card account number and the target payment state.

At S1005, the Internet financial platform server queries for a payment card attribute corresponding to the payment card account number, and makes a judgment on the payment card attribute corresponding to the payment card account number, and the process goes to S1006 if the payment card attribute is a non-default payment card for the target electronic device, and the process goes to S1007 if the payment card attribute is a default payment card for the target electronic device.

At S1006, the Internet financial platform updates a token state corresponding to a payment token which is stored in association with the payment card account number to be an unbound state, and then the process goes to S1008.

At S1007, the Internet financial platform updates a token state corresponding to a payment token which is stored in association with the payment card account number to be an unbound state, and deletes an association relationship between the payment token which is stored in association with the payment card account number and the target electronic device, and then the process goes to S1008.

At S1008, the Internet financial platform server sends fourth prompt information to the target electronic device.

At S1009, the target electronic device displays the fourth prompt information to prompt the user that the payment state of the payment card account number which needs to be unbound has been changed to an unbound state.

In a case where the payment card attribute corresponding to the payment card account number which needs to be unbound indicates a default payment card for the target electronic device, after the payment card account number has been successfully unbound from the target electronic device, the Internet financial platform server, when receiving a transaction request sent by an acquiring device which corresponds to the payment token stored in association with the payment card account number, may refuse to execute a transaction corresponding to the transaction request if it is found that the token state of the payment token is in an unbound state.

It should be noted that, after the user clicks an unbinding function, the token state corresponding to the payment token which is stored in the Internet financial platform server can be updated to an unbound state. The user may further click a loss-reporting function to enable the token state corresponding to the payment token which is stored in the Internet financial platform server to be updated to a loss-reported state. Specifically, a process for reporting loss of a payment card is similar to a process for unbinding the payment card, and will be not repeated here.

In addition, after the token state corresponding to the payment token which is stored in the Internet financial platform server has been updated to the unbound state or the loss-reported state, the user may further click a rebinding function or a loss-report canceling function to enable the payment token corresponding to the payment token which is stored in the Internet financial platform server to be updated to an activated state again, a process for which is similar to the process for unbinding the payment card, and will not be repeated here.

Therefore, in the embodiment of the application, there is a loosely coupled relationship between the target electronic device and a bound payment card account number and between the target electronic device and personalized data loaded in the target security element, which is dynamic mapping relationship. Therefore, during a sequent process for re-binding a default payment car, it will not cause frequent verification, download and rewriting processes for the card. Moreover, the target security element may store general personalized data for loading of the payment token, so that differences between personalized data of various card issuers can be eliminates, thereby improving compatibility of personalized data with various acquiring devices, so as to facilitate better industrial cooperation and promotion prospects.
